All stove vents should travel the shortest distance possible.You should avoid elbows or other bends if at all possible.
It depends a little on what is between the stove and the exterior wall but it might be possible and practical to take the duct off of the top of the hood and immediately turn it for the three feet to the exterior wall but it may cost you part of a lower cabinet. Quite apart from the already mentioned fire hazard of venting into the attic space, depending on your location, venting any warm moist air up into that space during cold weather, cold enough to condense moisture into water will result in water or ice forming under the roof decking and either damaging that or accumulating as ice which melts in the spring and comes down through your ceiling as water. You would be far better off going right up through the roof but having this done by a really good and competent contractor. The port can be sealed however I do agree that the fewer penetrations through the roof membrane the better. I don't much like the idea of your microwave oven venting into the attic space either.

I have a microwave which has a hood built into it. The motor was set for recirculation but has been changed to vent through the roof. I suppose I could change it to vent through the wall, but that would take it into the garage. The hole for the pipe has already been cut through the cabinet and ceiling . There is an exterior wall but it is about 3 feet to the right of the stove. The roof slopes down towards this wall, so I would imagine putting a vent there will be difficult if not impossible. Now what I could do is perhaps run the vent pipe up into the attic, then down the garage and vent it just above the garage door. This is where the roof peeks and I'd imagine putting a vent in the wall in this area would be much easier. Please let me know pros or cons of this idea.

Do not vent into the attic. In case of fire it will get into the attic and spread like, well like wild fire. Any grease exhausting with the fan will accumulate there and increase the fire risk. If the stove is on an outside wall it is usually not a difficult thing to mount an exhaust fan with the vent to the outside. Care should be taken to insure that the vent is gently sloped down toward the outside so that any condensate drains out with gravity. Finally, there is no real need to exhaust a kitchen range at all. There are often reasons why one might want to and in a very tightly sealed home it can help reduce the interior environmental moisture level and keep down kitchen cooking smells. for odors you can mount a recirculating fan which charcoal filters which do not exhaust outside. Personally I don't like the noise of the damn things. For some reason I don't understand they give me a discount on my house insurance because I do not have a kitchen vent. I do however have a duct to my air exchanger network near the kitchen stove. Hope this is helpful.

The old roof had a vent for the stove, but in their infinite wisdom, and their nack for executive decision making, my parents forgot to tell the roofers to install a vent in the new roof. Now, my mother doesn't want to cut a hole in the new roof for the vent because she's afraid it might leak. I suggested to her that we could try running the vent to an outside wall. But she goes on saying something like "why would you want to cut a hole in the building? It might leak, and with the amount of cooking you do, you don't need it." Yada yada yada. Needless to say, she doesn't want to install a vent. Her solution is to vent the stove into the attic. Her husband's dad says this is common. And it is true, I don't cook much, but I think this should be done right regardless. Now, the question. What is the best way to proceed if I want a vent to the outside? Should I consider having a vent installed in the roof or would the outside wall be better? Or is it fine just venting into the attic? Thanks for any info.
